Question

A cell is placed into a 3% dextrose solution. At that concentration, the solution is isotonic to the cell. If the concentration of dextrose in the solution is increased to 5%, the cell is now in __________.

Answer 1

Hypertonic solution

Step-by-step explanation:

Tonicity: The movement of water through the cell by osmosis is influenced by the extracellular solution.

Isotonic: There would be no net movement of water because the concentration of solution outside and inside of cell is same.

Hypotonic: The water will move inside the cell because the solute inside the cell is comparatively more concentrated.

Hypertonic: The water will move outside the cell because the concentration of solution outside the cell is greater.

If in 3% dextrose solution, the cell is in isotonic solution then adding the more dextrose to solute making 5% solution will increase the concentration of solution and cell will be in hypertonic solution.
